A moving tableau: a living shadow box.
Traditional theater elements separated from each other, then mixed.
Time moves only by way of the events on stage and their relationships.
The actions of the separate elements—actors, dancer, train, fog, light, screen—are events measuring spacetime relative to each other, requiring the viewer’s effort to induce meaning. Einstein is framed then unframed.
The diagonal is thematic, and simultaneity is a rehearsed accident.
